Application filed August 1T, 1886. Serial No. 211,136. (No model.)

To @ZZ whom it may concern:

Beit known that we, WILLIAM H. RIVERS and EDGAR WRIGHT, both citizens ofthe declare that the following is a full, clear-,and

eXact description of the invention, which will enable others skilled inthe art to which it appertains to make and use the sarne,reference beinghad to the accompanying drawings,

which form apart of this'spectcation, and inwhich- Figure l is aperspective View of so much of a spinning'niachine as is necessary toillustrate the application of this invention. Fig. 2 is aperspectiveview of the roller-beam having attached thereto a combined hinge andrest, also a combined hinge, rest, handle, and brace, each device beingshown closed in full lines and open in dotted lines; and Fig. 3 is avertical transverse section th rough the middle of the combined hinge,rest, handle, and brace.

Likeletters of reference indicate corresponding parts throughouttheseveral Vfigures.

This `invention relates to an improvement in spinning-machines; and itconsists in the iinproved construction and combination of partsvconstitutingsaidimprovement, as will be hereinafter fully set forth.

The object of this invention is to provide a ready and effective meansfor simultaneously raising all the guide-wire blocks of a ringspinningframe by tilting and automatically bracing the thread-board, to thefront edge of which said blocks are hinged; also, at the same time, toprovide for vertically adjusting said threadbOard. The means which areemployed in accomplishing this object consist offtwo devices, one ofwhich is an elaboration of the other.

The iirst device consists, as shown in the accompanying drawings, ofahinge-leaf, A,which is adj ustably'secured to the roller-beam B by ascrew-bolt, C, passed through a slot, D, in said hinge-leaf and a holein the roller-beam.

From the front of thishingeleaf arest,E, pro# jects horizontally. Therest is formed of a rectangular frame, into the center portion of whichfits one. end of the other hingeleaf, F,

when the hinge is closed. The leafF has one portion formed at rightangles to lthe other, the portion fitting into the rest being wider thanthe other portion, and serving for attachment to the thread-board N. Thenarrower portion has the hinge-pintle passed through its end, and restsin the upper part of the slot in the hinge-leaf A when the hinge isclosed. This rest aids in rigidly supporting the threadboard in itsoperative position,'and prevents undue strain upon the hinges of thesame whenV it is lowered after changing the bobbins.

-The second device, which is the more important part of the invention,is produced throughtransforming the first by cutting away the front partof the rest E and extending the broad portion of the hinge-leafF intothe handle G, which projects out in front of the guide- Wire blocks andtheir guide-wires. By means of this handle the thread-board can-beraised, and with it all the blocks M, which are separately secured toits front edge by means of hinges. The transformation also extends tothe lower part of the other hinge-leaf, which is prolonged, and its slotclosed at the bottom by the cross-piece H and spanned by. anothercross-piece, l, near the junction of said leaf and the rest, said restin its transformed shape consisting of the two arms J. The strengtheningfunction of the broken-away part of the rest is supplied by thecrosspiece I, which, together with the lower crosspiece, keeps the partsat the sides of the slot D from spreading apart. Then alever-brace, K,is added, provided with a notch in its lower edge, by which itisfulcrumed upon the crosspiece H. The

inner end of the lever-brace is shaped to engage a notch, L, formed inthe outer angle between the handle and the inner end of the leaf F, andthe outer end is weighted, so as to canse the upper end to readily fallinto said notch immediately upon raising the thread-board. The leverholdsthe thread-board up tillthebobbinshavebeen changed. Then theweighted end of the lever is raised and the thread-board lowered intooperative position.

`rlhese devices can be readily applied to any of the ordinary spinningmachines Without drilling any new holes in the roller-beam, since thebolts C can be passed through the holes formed for the bolts which holdthe old form IOL) of rests or braces under the thread-board. The

, slotsin said devices provide for their ready attachment to a beam, inwhich the old holes may be at variable distances from the upper edgethereof, and also for vertically adjusting the thread-board upon itsbeam.

Having thus 'fully described our invention, We clain1 1. rlhecombination, with the thread-board and roller-beam, of a slottedhinge-leaf provided With a rest projecting horizontally from its frontand a hinge-leaf in Which the attaching portion is formed at rightangles to the portion through which the hinge-pintle passes.

2. The combination of the thread-board and the roller-beam with thehingeleaf provided with a rest projecting horizontally from its frontand a hinge-leaf in which the attaching portion is prolonged intoahandle and formed at right angles to the portion through which thehinge-pintle passes.

3. The combination, with the thread-board and roller-beam, of a slottedhinge-leaf provided with rests projecting horizontally from its frontand a hinge-leaf in which the attaching portion is prolonged into ahandle formed at right angles to the portion through which thehinge-pintle passes, the inner end of the handle portion iitting betweenthe rests, and

t-he other portion fitting into the upper divis- 3o ion of'said slot.

4. The combination, with the thread-board and roller-beam, of a hinge-leaf secured to said threadboard, a slotted hinge-leaf secured to theroller-beam, a single bolt passed through said slot, .and a lever-bracepivoted vin the lower end of the slot. Y

5. The combination, with a thread-board and roller-beam, of a hinge-leafsecured to said thread-board, a slotted hinge-leaf secured to saidroller-beam and provided with a crosspiece at the lower end of the slot,and a weighted lever-brace provided with a notch in its under edge bywhich it is pivoted upon said crosspiece.

In testimony that we claim the foregoing as our own we have hereuntoaffixed our signatures in presence of two witnesses.
